Why my RAC nodes got rebooted by watchdog ?

Hi All

In the system message log we see that the NFS mounted third voting disk was not responsive.

There was 3 retry attempts before the nodes got rebooted. I checked the systems there is no modeprobe.conf file configured also the css diagwait is set to 0 .

Any idea what we can do ?

Our environment is RHEL 7 on VMware ESXi 5.5 VM's. The third votedisk is NFS mounted from a separate location and resides on a NAS Storage. 

Thanks & Regards
